NOTE (1): The data in these charts was compiled from information in <strong>Square</strong> D, <strong>Series</strong> <strong>Rating</strong> Data Bulletin<br />
No. 2700DB9901 and <strong>Square</strong> D Digest 171. <strong>Cooper</strong> Bussmann assumes no responsibility for the accuracy<br />
or reliability of the information. The information contained in the tables may change without notice due to<br />
equipment design modifications.<br />
NOTE (2): The line-side fused switch may be in a separate enclosure or in the same enclosure as the loadside<br />
circuit breaker. A line-side fused switch may be integral or remote.<br />
NOTE (3): Max fuse current rating denotes the largest amperage fuse that may be used for that series rated<br />
combination. A lower amperage fuse may be substituted for the listed fuse.<br />
